  • Full list of supported import and export formats and codecs: http://msdn.microsoft.com/en-us/library/hh973634.aspx
  • Remarks:Third-party SDK for HLS on Windows RT and Windows Phone 8: http://3ivx.com/technology/windows/metro/http_live_streaming.htmlThird-party SDK for IIS Smooth Streaming on Android in-app: http://axinom.com/en_axinom_news_android_sdk.AxCMS (there are others)Android supports HLS natively only since 3.0, and there are some issues with this support (browser and in-app): http://www.longtailvideo.com/blog/31646/the-pain-of-live-streaming-on-android/Also see: http://en.wikipedia.org/wiki/HTTP_Live_Streaming#Clients for some more links and details
  • Example:Encoding a 200MB video to both IIS Smooth Streaming and HLS formats in various bitrates may produce 800 MB of output, for a total of 1GB encoding I/O. Total cost: $1.99.Storing the 800 MB of output would cost approximately $0.06 per month (without geo-replication).Streaming the 200 MB video to 10,000 clients per month (assuming 50% average consumption rate) = 976GB would cost approximately $117 per month.
  • Illustrate the creation of a new media service.Upload a small mp4 asset. (clipcanvas…mp4)Publish the source (show that the URL is a simple blob storage URL).Use the built-in test player for the source, or simply copy the URL to the browser (this is a progressive download player).Encode the asset for HLS. Explain that there is an intermediate step that encodes to IIS Smooth Streaming and then creates an additional manifest for HLS.Monitor job progress.Publish both the intermediate IIS Smooth Streaming output and the HLS output.Use the built-in test player for IIS Smooth Streaming playback.Use an iPhone/iPad/iOS Simulator for HLS playback.
  • Show the SimpleUploadEncodeDeliver demo console application:Review the code that creates an asset, gets a storage URL (locator) for uploading the asset, and uploads it.Review the code that configures the encoding job (MP4 ==&gt; IIS Smooth Streaming ==&gt; Apple HLS).Review the code that waits for the encoding job to complete.Review the code that generates the final streaming URLs.(This code was taken from the walkthrough that you see on the dashboard of every new Media Service.)
  • Show HTML5 page on Mac, Windows, iPad (progressive download with &lt;video&gt; element) – from IBA portalShow Silverlight page on Mac, Windows – from IBA portalShow iOS app with MediaPlayer framework
  • Demonstrate the IBA pilot “CMS” running end-to-end on Windows Azure.Upload a media file:curl -X POST http://wams-sdp13.azurewebsites.net/Home/Upload?file=test.mp4 --data-binary @test.mp4Wait for encoding to complete.Demonstrate the resulting URLs on Windows / OS X / iOS.Demonstrate the SkyRocketMedia CMS: http://www.skyrocketmedia.netWalk through the different screens, explain that it is a nice wrapper on top of the Azure portal.

    11. 11. MANAGING AND PLAYING ASSETS
    12. 12. Ingesting Assets from the .NET SDK Obtain a CloudMediaContext • Gives you access to all objects and APIs Create an asset (IAsset) • A collection of media files Create a file (IAssetFile) • A single file within an asset Create an access policy and locator • Determines ACL for asset and provides a URL for upload
    13. 13. Encoding Assets from the .NET SDK Obtain a media processor (IMediaProcessor) • Media processors can encode and package assets Create an encoding job (IJob) • A job is a set of tasks for Media Services Add tasks to the job (ITask) • E.g., encode WMV file for Apple HLS • Tasks have input assets and output assets Monitor job progress until it completes
    14. 14. Delivering Assets from the .NET SDK Locate the output asset for a job Create an access policy and locator Generate URLs • For progressive download • For streaming (IIS/HLS) Optional: Enable CDN • For progressive download (blob storage) • For streaming origin server
    15. 15. Uploading and encoding an asset from the .NET SDK DEMO
    16. 16. Playing Progressive Download Assets • For progressive download in browsers that support HTML5 video, use the <video> element <video width="640" height="480" controls> <source src="@Html.Raw(Model.Mp4SourceUrl)" type="video/mp4" /> </video>
    17. 17. Playing IIS Smooth Streaming • For PC and Mac delivery of IIS Smooth Streaming, use the Silverlight Smooth Streaming SDK – Sample player available on CodePlex – http://playerframework.codeplex.com/ <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" Server-hosted Silverlight player width="100%" height="100%"> <param name="source" value="/Content/SmoothStreamingPlayer.xap"/> <param name="InitParams" value="mediaurl=@Model.SilverlightStreamingUrl"/> </object> Parameters for player
    18. 18. Playing HLS In-App on iOS • The iOS MediaPlayer framework natively supports Apple HLS URLs self.player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:...]]; self.player.scalingMode = MPMovieScalingModeAspectFill; self.player.controlStyle = MPMovieControlStyleDefault; [self.view addSubview:self.player.view]; [self.player play];
